Which of the following is the best definition of literary criticism?
a. an interpretation of a work of literature supported by quotations details and personal responses
b. an essay about the flaws contained in a work of literature
c. a book review written by a professional critic for publication
d. an alternate ending to a work of literature

The correct answer is A. An interpretation of a work of literature supported by quotations details and personal responses.
B is incorrect because a literary criticism doesn't have to do with flaws only - it can show both the good sides and the bad ones. C is incorrect because it doesn't have to be a book. D is incorrect because a literary criticism refers to somebody's thoughts about a certain literary work, interpretations, etc.

It is to persuade someone(make them think it’s is right ) to them understand why it is right
